KuyiniI-MCCB (Isiphuli Sesekethe Esibunjiwe)
Ukuphepha kubaluleke kakhulu emkhakheni wobunjiniyela kagesi. Ukuqinisekisa ukuvikelwa kwezinhlelo zikagesi nokuvimbela ukwehluleka okungenzeka, kubalulekile ukusebenzisa ama-circuit breaker athembekile. Phakathi kwezinhlobo ezahlukene ezitholakalayo,i-molded case circuit breaker (MCCB)Ivelele njengengxenye ebalulekile. Inhloso yalesi sihloko ukuxoxa ngencazelo, izimiso zokusebenza, izinhlelo zokusebenza, izinzuzo kanye nemikhuba yokulungisa enconywayo yama-molded case circuit breakers ngendlela esemthethweni ukuze kukhanye lesi sici esibalulekile semishini kagesi.
I-MCCB, eyaziwa nangokuthi i-molded case circuit breaker, iyithuluzi likagesi elisebenza ngezindlela eziningi elisetshenziselwa ukuvikela izinhlelo zikagesi ekugcwaleni ngokweqile, i-short circuit kanye nezinye izinkinga zikagesi. Ngokungafani nama-miniature circuit breaker asetshenziswa ezindaweni zokuhlala,Ama-MCCBzinamakhono wamanje aphakeme futhi ngenxa yalokho zifanelekela ukusetshenziswa kwezimboni nezentengiselwano. Lawa ma-circuit breaker afakwe indlela yokugibela ethuthukisiwe ethola ukugeleza kwamanje okungavamile futhi iphazamise i-circuit ukuze ivikele imishini exhunyiwe.
Ama-MCCBzisebenza ngesimiso sesenzo se-thermomagnetic futhi zenzelwe ukusingatha ngempumelelo izimo zokulayisha ngokweqile kanye nezesekethe esifushane. Izinto ezishisayo zisabela ekushiseni okuhamba kancane, kwesikhathi eside, kuyilapho izinto ezimagnetic zisabela ezisekethe ezimfushane ezisheshayo ezinzima kakhulu. Le ndlela ekabili iqinisekisa ukuvikelwa okuthembekile emaphutheni ahlukahlukene kagesi, okwenzaAma-MCCBukukhetha okuthembekile konjiniyela bakagesi abasebenza kumaphrojekthi ahlukahlukene.
Ngenxa yomklamo wayo oqinile kanye nesilinganiso samandla aphezulu,Ama-MCCBzisetshenziswa kabanzi ezimbonini ezahlukahlukene. Kusukela ezitshalweni zikagesi kanye neziteshi ezincane kuya ezindaweni zokukhiqiza kanye nezindawo zezentengiselwano, ama-case circuit breaker abunjiwe adlala indima ebalulekile ekuqinisekiseni ukugeleza kukagesi okungaphazamiseki. Angasetshenziswa ezinhlotsheni ezahlukene zikagesi, kufaka phakathi ukukhanyisa, ukulawula imoto, ukuvikelwa kwe-transformer, ama-switchboard, njll., ukuvikela ngempumelelo imishini nabasebenzi ezingozini zikagesi.
Enye yezinzuzo eziyinhloko ze-Ama-MCCBikhono labo lokusingatha imithwalo yamandla aphezulu.Ama-MCCBngokuvamile zilinganiswa kusukela kuma-amps ayi-10 kuya ezinkulungwaneni zama-amps, ukuze zikwazi ukuphatha ngokuphephile imithwalo kagesi esindayo evame ukutholakala ezindaweni zezimboni. Ngaphezu kwalokho, lawa ma-circuit breaker anikeza izilungiselelo zokuhamba ezilungisekayo, okuvumela onjiniyela ukuthi bahlele izinga lokuvikelwa ngokwezidingo ezithile zesistimu kagesi. Lokhu kuguquguquka kuqinisekisa ukusebenza kahle futhi kuthuthukisa ukuphepha kwamadivayisi axhunyiwe.
Ukuqinisekisa ukuthembeka kwesikhathi eside kwama-molded case circuit breakers, ukulungiswa njalo kubalulekile. Ukuhlolwa njalo nokuhlolwa kuyanconywa ukuze kutholakale noma yiziphi izimpawu zokuguguleka, ukuxhumeka okuxekethile noma ukwehluleka kwezingxenye. Ngaphezu kwalokho, ukulandela imihlahlandlela efanele yokufaka kubalulekile ukuvimbela noma yimuphi umphumela omubi ekusebenzeni kwe-circuit breaker. Kubalulekile futhi ukugcina indawo ezungezile ihlanzekile futhi ingenalo uthuli kanye nemfucumfucu engathinta ukusebenza kwayo. Ukulandela le mikhuba yokulungisa kuzokwandisa impilo ye-I-MCCBfuthi kuncishiswe ingozi yokwehluleka kukagesi okungenzeka.
Ngamafuphi,i-molded case circuit breaker (MCCB)iyithuluzi likagesi elibalulekile ukuqinisekisa ukusebenza okuphephile kwezinhlelo ezahlukene zikagesi. Ama-MCCB asetshenziswa kabanzi ezindaweni zezimboni nezentengiselwano ngenxa yekhono lawo lokuvikela ekuthwaleni ngokweqile, amasekethe amafushane, kanye nezinye izinkinga zikagesi. Isilinganiso sayo samandla aphezulu, izilungiselelo zokuhamba ezilungisekayo, kanye nokuthembeka kwenza kube kuhle konjiniyela abafuna ukuvikelwa kukagesi okusebenzayo nokuphephile. Ngokulandela imikhuba yokulungisa enconyiwe, impilo yeI-MCCBkungathuthukiswa kakhulu, okusiza ekuphepheni nasekuthembekeni kwesistimu kagesi iyonke.
